What should you do when driving in fog?

When driving in fog, using low beam headlights and reducing your speed is crucial for safety. Low beam headlights are designed to illuminate the road immediately in front of your vehicle without reflecting off the fog and creating glare, which can impair visibility even further. Reducing your speed is essential because fog often means reduced visibility, and the stopping distance is longer in low visibility conditions. By slowing down, you give yourself more time to react to any obstacles or changes in the traffic situation. This combination of using low beams and decreasing speed helps ensure that you can see and be seen by other drivers, significantly enhancing safety when navigating through foggy conditions.
